Overview

Saccharomyces ferment lysate filtrate is a variation of another INCI ingredient – Saccharomyces lysate extract. There is no significant difference between them; both are humectant ingredients made from Saccharomyces yeast culture, and both contain various enzymes, amino acids, vitamins, and beta-glucan.

The only difference is that this ingredient is labeled as "filtrate", meaning that the mixture has been filtered to remove larger cellular fragments and leave only what is dissolved in the medium.
